AIK1 — Nicotiana attenuata

Summary

A4A49_00800 (AIK1/NPK1) in coyote tobacco encodes a protein with serine/threonine kinase activity, including MAPKK and MEKK activity, and belongs to the plant MAPKKK family. It is associated with diverse molecular functions such as ABC-type transporter, auxin efflux transporter, and cadmium ion transmembrane transporter activities. The gene is linked to biological processes including cytokinesis, regulation of defense response by callose deposition, lateral growth, and cellular detoxification. It has been connected to traits including auxin content and sensitivity, jasmonic acid content, leaf senescence, root thickness, seed growth, flowering time, and disease tolerance. Associations with phenotypes include herbivore resistance, salt and osmotic stress tolerance, abscisic acid sensitivity, stomatal response, and defense against biotrophic pathogens. Studies of related genes in other species link the family to grain dormancy, root length, and drought resistance.
